6 Claims.

My invention relates to apparatus for carbonating and dispensing liquids and more particularly to apparatus of that character for charging water or beverages of diverse character in, 5 and dispensing the charged water or beverages from, a container of ordinary siphon bottle type.

Charged water for beverages, or other uses, has heretofore been supplied in containers known as siphon bottles for'individual use, as distinguished from the large commercial containers, but it has been the practice to iill the bottles at a centralplant and to return the bottles to the plant for refilling.

the purpose is available.

It is the object of my present invention to provide apparatus for use in connection with bottles of siphon type, or other ycontainers, whereby water contained within a bottle, or the like, may be charged with gas emanating from a contained quantity of solid carbon dioxide and the charged contents thereof dispensed from the bottle as required.

In Aaccomplishing this object, I have provided improved details of structure, a preferred form of which is illustrated in the accompanying drawing, wherein:

Fig. 1 is a central vertical section of a portion of apparatus embodying my invention, illustrat, ing its application to a Siphon bottle.

Fig. 2 is a horizontal section on the line 2-'2 Fig. l.

Fig. 3 is a vertical section on the line 3-3 Fig. 1.

Referring more in detail to the drawing: 1 designates a. container of ordinary Siphon bottle type having a neck 2 provided with the usual bead 3. 1

Mounted on the neck 2 is a carbonating and dispensing apparatus embodying my invention including a collar 4 permanently xed to the neck of the bottle by cement 5, or otherwise, with its upper edge terminating flush with the edge of the bead 3.

6 designates a cap, or housing, element of the apparatus, threaded connection between a base removably attached to the bottle by ring 'I of the cap member and the collar 4 on the bottle; the cap 6 having a central chamber 8 on its upper end of less diameter than the internal diameter of the ring 7 to form a closed space for the solid carbon dioxide container presently mentioned.

The difference in diameter between the ring 7 and chamber 8 provides a downwardly facing shoulder 9 within the cap for accommodating a packing member 10 which is, by the shoulder 9, pressed against the edges of the bottle neck and retainer ring when the cap is screwed to place. A cup or container 11 seats on the packing member 10 and is pressed thereagainst by contact of the top wall of the chamber 8 with the upper edge of the open top of the cup, so that the cup, when in place, is sealed by the top of the cap. The cup 11 is dimensioned for snug t within the chamber 8 and of such inside capacity as when full to contain a proper quantity of solid carbon dioxide for charging a full quantity of water or beverages in the bottle to a predetermined and practically constant carbon dioxide content or pressure.

Threaded into the bottom of the cup 11 and extending through the packing member 10 to near the bottom of the bottle is a tube l2 provided at its lower end with a diffusing nozzle 13, preferably comprlsing a plurality of spaced disks or plates 14 and interposed rings 15 of fine screen wire sleeved over the tube and retained thereon in clamped condition between upper and lower nuts 16 and 17 threaded on the tube. The lower end of the tube is provided with an upwardly opening check valve 18 and side openings 19 are formed in the tube immediately above the check valve.

By means of the diffuser nozzle, as evolved from the solid carbon dioxide in the cup l1 may be delivered into the liquid by the inherent pressure developed Within the cup on sublimation of the solid carbon dioxide. The cup l1 holding the solid carbon dioxide is affected by atmospheric temperature only as apart from the heating capacity of the water solution to be charged so that sublimation is kept at a reduced rate; a factor which together with minute diffusion, caused by passage of the gas through the screens, promotes a uniform absorption without danger and without requirement of agitation. This is of particular benefit when the charged contents are to be discharged immediately and where in the application to larger containers than the usual Siphon bottle a shaking or agitation of the large container cannot be had.

The ball check in the lower extremity of the the bottle as presently more fully described.

Opening through the side wall of the cup 11 is a port 20 through which charged water may be delivered from the bottle under valve control. 21 designates a pin seated in vrecesses in the cup and cap Walls for keeping the cup to maintain communication of the cup with an outlet chamber presently described.

22 and 23 designate handle members attached to the cap 6, preferably by means of Shanks 24 threaded onto sockets 25 within the cap, the handles being preferably paired on opposite sides of the cap to provide symmetric appearance and one of the handles, 23, being constructed to form a dispensing nozzle.

The handle 23 has a valve chamber 26 opening through its inner end for communication with the outlet port 20 of the carbon dioxide container and an outer port 27 separated from the chamber 26 by a wall 28 having a port 29 provided with ribs 30 forming a guide for a valve stem 31, the outer end of the port 2'7 being counter bored at 32 to provide a guide for the neck 33 of a push button 34 which is adapted to seat in a second counter bore 35 in the end of the handle member 23.

A valve 36 on the inner end of the stem 31 is adapted to seat against the bottom of the chamber 26 to close the port 29 and a spring 37 surrounding the stem between the inner end of the port 27 and the inner end of the button neck 33 normally yieldingly retains the valve on its seat.

Opening from the counter bore 32 in the end of the handle is a port 38 communicating with the throat 39 of a nozzle 40, the outer end of the throat being preferably ared in accordance with ordinary practice.

Apparatus constructed as described is assembled with a bottle, filled with water or a beverage, by projecting the tube into the bottle so that the packing element and solid carbon dioxide container assembled on the tube will rest on the neck of the bottle. A quantity of solid carbon dioxide is then placed in the cup and the cap of the apparatus threaded onto the retainer ring on the bottle.

Carbonio acid gas sublimating from the solid material passes downwardly into the tube, but is diverted by the normally closed check valve through the side openings and screen rings into the water or other liquid in the bottle, charging the water and accumulating in the top of the bottle above the water.

The complete diiusion of the gas by the screen results in rapid charging of the liquid and after the carbon` dioxide has completely gasifled, the bottle is ready for use in the ordinary manner by manipulation of the outlet valve, it being apparent that the liquid under pressure of the gas will readily elevate the ball check from its seat to permit outflow of liquid from the bottle.

It will further be apparent that pressure of the gas supplements tension of the spring in holding the outlet valve 36 to its seat to prevent dissipal.
